Everything about microspheres and research utilizing precision spherical particles.

Fluorescent Glass Microspheres

Fluorescent Red Coated Soda Lime Glass Microspheres

Solid glass microspheres hemispherically coated with fluorescent coatings, a fluorescent coating is precisely applied to half of the core sphere, making the glass spheres appear colorful and fluorescent at daylight and exhibit bright fluorescent response under UV light.

Advantages of Borosilicate Glass Microspheres in 0.03mm to 0.2mm sizing

High quality glass microspheres for research and development are always in high demand.? In an effort to better serve scientists Cospheric recently added a complete line of high quality borosilicate microspheres, and microbeads.

Borosilicate glass offers? advantages over standard soda lime glass microbeads.

  • Roundness is >90%?? (Soda lime >85%)
  • Density is the lowest of most glasses at 2.2g/cc? (Soda Lime 2.5g/cc)
  • Very low thermal expansion coefficient? 32×10-7/?C?? (for 30-300?C)?? (Soda Lime:? 90×10-7/?C)

The high roundness, and low thermal expansion make borosilicate spheres an excellent candidate for use as spacers in epoxy bond lines, or other applications which require stability over a wide temperature range.

Borosilicate glass spheres are now offered in narrow size ranges from 0.03mm to 0.2mm with greater than 90% of the particles in range.
